“…PRIME specification defines an optional convolutional encoder for certain modulation schemes. A previous study from the authors concluded that modulation schemes without convolutional encoder are not efficient for real field scenarios [10], an observation that is consistent with other studies [17,18].…”

Narrowband (NB) powerline communication (PLC) is extensively adopted by utilities for the communication in advanced metering infrastructure (AMI) systems. PLC technology needs to overcome channel disturbances present in certain grid segments. This study analyzes improvement proposals of the physical layer of the main narrowband PLC technologies approved by international communication organizations that are currently deployed in Europe: Powerline Intelligent Metering Evolution (PRIME) 1.3.6, PRIME 1.4, and G3-PLC, in order to improve PLC performance under channel disturbances. This thorough study is based on simulations carried out by an innovative ad hoc Virtual PLC Lab, developed by the authors, applied in replicable, fully-automated, and cost reduced test scenarios. The analysis is performed by applying standardized test methods and metrics, and by evaluating the influence of a set of representative channel disturbances defined by the European Telecommunications Standards Institute (ETSI) and selected noises generated by distributed energy resources (DER) in normal operation. PLC performance improvements in terms of equalizer curve fitting, error correction codes, and noisy subcarrier suppression mechanisms are presented. The performance gain due to each physical improvement proposal is accurately measured and compared under the same conditions in a replicable and automated test environment in order to evaluate the use of the proposals in the evolution of future PLC technologies.As a result, sophisticated test methods are needed to evaluate, first, the effects of each type of disturbance on the different configurations of the communications technologies and, second, the efficiency of the strategies designed to overcome such disturbances. This paper proposes the use of a Virtual PLC Lab to evaluate the performance of several improvement proposals for several PLC technologies. The Virtual PLC Lab includes the whole communication system, composed not only of transmission and reception devices, but also on the characterization of the different effects of the propagation channel. As a result, it enables an efficient analysis of new coding or equalizing techniques that would require long and complex validation procedures, without the need of physically implementing these techniques in the hardware devices, reducing the time and the cost of these developments.Several articles study the NB PLC performance from 3 to 500 kHz in the presence of noise and harsh situations. This performance has been studied from multiple approaches. There are analytical studies based on generic PLC technologies [2]. Several studies are oriented to PRIME statistical performance in field setups [3,4]. Some specific studies focus on upper layer performance instead of being physical layer-oriented [5]. There are some comparisons of the performance of PLC technologies and physical layers, although these are not exactly under the same conditions [6]. Moreover, there is a lack of studies covering the PRIME standard in its recent 1.4 version and G3...

Communication is the transfer of information from one point to another over a channel. However, as technology is growing, more information is needed to be passed over large distances for the realization of the world being a global village. There is the need to place a reliable communication system that will transmit effortlessly both data and voice over a channel. Power Line Communication (PLC) also known as Broadband over Power Line (BPL) technology offers high speed and broadband communication services to homes connected to the power lines. This makes use of the electrical lines for transmission of data up to the last mile and there is no need of separating copper cables, short haul satellite systems, optical fibre cable and Wi-Fi. This work presented an overview of a voice and data communication over PLC in terms of the various types, equipment use, method of communication, application, regulatory activities on PLC and the challenges facing the implementation of power line for transmitting voice and data. Therefore, PLC is a viable alternative to all other methods of transmission as it is readily available and can be easily implemented in rural areas where other communication systems are not implemented for the transmission of voice and data communication.

“…According to [3], some tangible deliverables from smart grid initiatives include real-time pricing, demand response (DR), electric vehicle charging control, integration of distributed Furthermore, many smart grid applications require low data rate; hence, it is understandable that NPLC dominated previous discussions [9][10][11][12][13][14], and funded projects such as [15][16][17][18][19] in relation to smart grids and their applications in low voltage (LV) regions. Apart from electromagnetic compatibility (EMC) issues in PLC generally [20,21], other major arguments against BPLC have been that 2-30 MHz cannot traverse an medium voltage/low voltage (MV/LV) step-down transformer without external bypass coupling circuit and that it suffers from high attenuation with distance [6].…”

Broadband PLC for Clustered Advanced Metering Infrastructure (AMI) Architecture

Advanced metering infrastructure (AMI) subsystems monitor and control energy distribution through exchange of information between smart meters and utility networks. A key challenge is how to select a cost-effective communication system without compromising the performance of the applications. Current communication technologies were developed for conventional data networks with different requirements. It is therefore necessary to investigate how much of existing communication technologies can be retrofitted into the new energy infrastructure to cost-effectively deliver acceptable level of service. This paper investigates broadband power line communications (BPLC) as a backhaul solution in AMI. By applying the disparate traffic characteristics of selected AMI applications, the network performance is evaluated. This study also examines the communication network response to changes in application configurations in terms of packet sizes. In each case, the network is stress-tested and performance is assessed against acceptable thresholds documented in the literature. Results show that, like every other communication technology, BPLC has certain limitations; however, with some modifications in the network topology, it indeed can fulfill most AMI traffic requirements for flexible and time-bounded applications. These opportunities, if tapped, can significantly improve fiscal and operational efficiencies in AMI services. Simulation results also reveal that BPLC as a backhaul can support flat and clustered AMI structures with cluster size ranging from 1 to 150 smart meters.
